Costeño Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let's take a good, long look at what's coming down the pipe for Costeño Beach over the next couple of weeks. Straight up, this isn't a time to be booking a flight for a surf trip; it's more of a "keep your board in the car and your fingers crossed" kinda forecast. The surf window is open from this Sunday the 16th right through, but it's mostly a story of small, weak, short-period swells and less-than-ideal wind angles.

We start off this Sunday morning, the 16th, with some small 4ft NE windswell washing in. The energy is pretty weak at 205, and the wind is a light cross-on breeze from the ENE, so it'll be a bit bumpy. Conditions are marginal, but it’s surfable for a beginner. Through Sunday and into Monday the 17th, the swell ticks up a bit to 5ft - 6ft, but the energy climbs into the moderate range (up to 867) and we’ve got those persistent cross-onshore winds. The water temp here is sitting at 82°, which is totally normal for this time of year.

The standout window looks like Tuesday morning, the 18th. It won't be big—just 4ft—but we get a rare moment of glassy conditions from the NNW. That 8-second period NE swell will be super clean, making it the best session for the first week. The energy is moderate at 125, so don't expect bombs, but the lack of wind will make it feel ten times better.

After that, it’s a bit of a grind. From Wednesday the 19th through the 25th, we see a lot of those same cross-on winds and marginal conditions. Swell stays between 4ft and 6ft, but the period is short (6-8 seconds) and the energy often pushes into a moderate range (200-400). It’s not terrible, but it’s the definition of ordinary. Thursday the 27th afternoon looks promising again, with a clean 6ft NE swell and glassy winds. That’s a solid wave size for the area and the energy hits 413, making it a contender for the best of the run if the wind holds.

As we push into the second week, the energy really drops off. By Sunday the 30th, we're looking at tiny 3ft to 4ft waves with energy under 100 (71-86). The period is only 6 seconds. That’s just not going to get the heart racing. The best bet in that last stretch is Wednesday the 26th morning, with glassy conditions on a 4ft swell (energy 202), but it's another small wave day.

Honestly, for the whole 16-day window, the only truly clean, glassy sessions that stand out are Tuesday morning the 18th, Thursday afternoon the 27th, and maybe Wednesday morning the 26th. The rest is a mix of bumpy wind, small swell, and poor quality. If you’re a beginner, plenty of these days will be manageable thanks to the consistent 3ft-5ft range, but for anyone looking for a proper groomed wave, you have to be patient and pick your windows. It's not a blank run for the area, but it's a slow, ordinary period. Keep an eye on that glassy wind; that's the golden ticket here.

Stay tuned, and don't put the board away just yet.

Rusty.
